Internals: Move CReset under Assign (#6978) 2026-01-31 21:27:36 -05:00
Geza Lore d9234501e0
Optimize concatenations that produce unused bits in DFG (#6971) 
Concatenations that are only used by Sel expressions that do not consume
some bits on the edges can be narrowed to not compute the unused bits.

E.g.: `{a[4:0], b[4:0]}[5:4]` -> `{a[0], b[4]}[1:0]`

This is a superset or the PUSH_SEL_THROUGH_CONCAT DFG pattern, which is
removed.

Christian Hecken 8b2144a9db Fix memory leak in vpi_put_value and vpi_get_value 
PR #6704 introduced the getForceControlSignals function to
verilated_vpi.cpp. It returns a pair of vpiHandles. These handles were
not released, causing a memory leak. This commit fixes this, in addition
to other minor changes for speed and readability that did not make it
into #6704.

No functional change intended.
